Intraoperative medial wall disruption in Dega pelvic osteotomy: Does it effect the radiographic outcome at...

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Radiographic analysis

Background:

• Developmental dysplasia of the hip (DDH) often requires surgical intervention.
• Dega pelvic osteotomy is a common surgical technique for treating DDH.
• Medial wall disruption is a potential complication during Dega osteotomy.

Purpose of the Study:

• To compare radiographic outcomes in patients undergoing Dega osteotomy with and without medial wall disruption.
• To assess the effect of medial wall disruption on acetabular index (AI) and long-term correction.

Main Methods:

• Retrospective review of 95 hips treated with Dega osteotomy for DDH.
• Patients divided into two groups: medial wall disruption (Group A) and no disruption (Group B).
• Anteroposterior pelvic radiographs analyzed for AI changes preoperatively, postoperatively, at 12 weeks, and at last follow-up.

Main Results:

• No significant difference in acetabular index (AI) between groups at any time point (preoperative, postoperative, 12 weeks, last follow-up).
• Comparable radiographic correction achieved during surgery and follow-up in both groups.
• Excellent or good results achieved in 91% of patients with medial wall disruption and 90% without (p=0.944).

Conclusions:

• Disruption of the medial wall during Dega osteotomy does not significantly impair radiographic correction.
• Medial wall integrity is not a critical factor for successful radiographic outcomes in Dega osteotomy.
• The study supports the continued use of Dega osteotomy even with incidental medial wall disruption.
